characters in each of the views and, in which:

Fig. 1 is a longitudinal sectional view through a pulley made accordingto my invention, indieating a clothes line in dot and. dash lines.

Fig. 2 is a section On the line 2-2 of Fig. 1 with part of theconstruction shown in elevation and with parts broken away.

Fig. 3 is a section on the line 3-3 of Fig. l; and

Fig. 4 is a detailed view of one of the wiper elements which I employ,detached.

In the construction shown, I provide a pulley which is fashioned fromtwo substantially similar casing parts l6, If), each part havinginwardly set hub portions l I, II for support of the pulley axis l2 inthe form of a rivet pin. The casing parts, when assembled, by rivetingtogether two projecting flaps or flanges l3 as by the rivet I4, and byturning-over hook flange portions, as at I5, form a disc-type casinghaving two tubular admission and discharge extensions, as at It and II,as clearly illustrated in Fig. 1 of the drawing, and also shown in Fig.3 of the drawing. The hook-shaped flanges l5 are formed on wall portions18, which join the tubular portions II, as clearly seen in Fig. 3 of thedrawing and these wall portions are pressed outwardly to form alongitudinal channel I9 for purposes later described.

Mounted on the rivet pin M is a coupling or hanger loop 20.

Arranged around the axis I2 are a series of ball bearings 2|, note Fig.l, which are arranged between the separate parts 22, 22' of the pulleywhich is disposed in the casing, these pulley parts beingsecuredtogether by welding, as indicated at 23 in Fig. 1 of the drawing. Inconjunction with the casing or the separate parts [0, l0 thereof, stillmore particularly, in connection with the tubular extensions l6, l! aretwo similar wiper elements 24, each element comprising a twisted wirestrand having a long mounting end 25 and a short mounting end 26, theintermediate portion of the strand having a suitable brush body 21 ofring-like or annular construction. In. other words, that part of thetwisted strand, on

Ids-256.6)

. 2 which the brush body is arranged, is shaped into circular form, soas to provide an opening 28 centrally of the brush body which ispreferably smaller in diameter than the outside diameter of the clothesline tobe passed therethrough, which clothes line is indicated indot-dash lines at 29 in Fig, 1 of the drawing and also indicated in Fig.3 of the drawing. In assembling the parts of the pulley casing, two ofthe elements 24 are arranged between the walls It in the channel I9 withthe long ends 25 of the elements overlapping each other, as clearly seenin Fig. 3 of the drawing. In final assemblage of the casing parts, thewalls l8 are preferably crimped together, as indicated at 30 in Fig. 3,so as to securely bind the elements 24 in position to maintain theopenings 28in suitable centralizedposition within the tubular portions16 and H of the casing. 7

With this construction, it will be apparent that, as the clothes line 29is passed around the pulley, the clothes line will be frictionallypassed through the circular or ring-like wiper elements, or brush bodies27 of the wiper elements and any deposits that may be present on theline will be removed and the line kept clean for the intended use. Itwill be recommended that, preparatory to using the line, the line willbe run through the pulleys a number of times for this purpose.

By constructing both parts of thecasing and the pulley of similarlyshaped members'and'by utilizing two wiper elements o-f similarconstruction, the cost of producing the entire device is materiallysimplified. Thus the pulley can be sold at a relatively reasonableprice. While in the present construction, I haveillustrated certaintypes of wiper or cleaner elements, the structure of these elements maybe modified to suit the intended uses, particularly in pulleys of anytype or kind. In some instances, where a strand-like body is passedaround a pulley member, these elements may be utilized for any purposeconsistent with the results that may be desired.

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent is:

l. A clothes line cleaner comprising two substantially similar casingparts forming a hollow body, in which a pulley is mounted for freerotation, tubular projections on said body, the easing parts havingabutting wall portions between said tubular projections, said wallportions having registering recesses on adjacent surfaces thereofopening into said tubular projections, wiper elements arranged in thetubular projections and having overlapped mounting ends disposed in saidrecesses, means securing the casing parts together, and means retainingthe mounting ends of said elements within and against displacement fromsaid recesses.

2. A clothes line cleaner comprising two subtantially similar casingparts forming a hollow body, in which a pulley is mounted for freerotation, tubular projections on said body, the cas ing parts havingabutting wall portions between said tubular.- projections, said-wallportions having registering recesses on adjacent surfaces thereofopening into said tubular projections, wiper elements arranged in thetubular projec'-- tions and having overlapped mounting, ends disposed insaid recesses, means securing the casing parts together, means retainingthe: mounting" ends of said elements within and against displacementfrom said recesses, and said lastnamed means comprising indentures onthe wall portions of the casing parts engaging overlapped portions of.the mounting ends of saidelements.

3. 4 clothes line cleaner com-prising two substantially similar casing.parts forming a hollow body, in which a pulley is mounted: for freerotation, tubular projections on said body, the casing parts havingabutting wall portions between said tubular projections, said wallportions having registering recesses on adjacentsurfaces thereof openinginto saidv tubular projections, wiper elements arranged in the tubularprojections. and having overlapped mountin endsdisposed in saidrecesses, means securing the casing parts together, means retaining themounting ends of said elements. within and against displacement fromsaid. recesses, said last named means comprising indentures onthe wallportions of the c'asingparts engaging overlappedportions of the mountingends of said elements, and said elements comprising brush bodies.

4. A. clothes line cleaner comprising twosubtantially similar casinparts: formin a hollow body, in which a pulley is'mounted forfreeroparts together, means retaining the mounting" ends of said elementswithin and against displacement from saidrecesses, said last named 5. Aclothes line cleaner comprising two substantially similar casing partsforming a hollow body, in which a pulley is mounted for free rotation,tubular projections on said body, the casing parts having abutting wallportions between said tubular projections, said wall portions havingregistering recesses on adjacent surfaces thereof opening into saidtubular projections, wiper elements arranged in the tubular projectionsand having overlapped mounting ends disposed in said recesses, meanssecuring the casing parts together, means retaining the mounting ends ofsaid elements within and against displacement from saidrecesses, andsaid elements comprising ring'b'odies disposed within said tubularprojections.

6. A pulley frame comprising similar casing parts, a p'ulleyrotatablymounted in said frame, upper and lower portions of the frame havingtubular portions in alinement with opposed peripheral portions of saidpulley, a ring body of yielding material in one of said tubularportions, andv means retaining said ring body against displacement fromsaid frame.
